[Tim’s] miniMAME‘s construction follows the “light and cheap” approach, using foam core board and hot glue. Sure it won’t last a nuclear attack, but at least it’s light enough to carry to a friend’s house.

With a removable netbook at the core, CCFLs, speakers, trackball, and mini arcade fighting stick, the project completely surpassed our expectations. For those looking to build a miniMAME, [Tim] includes lots of pictures, details, and plans allowing anyone to make their own in about an afternoon.

Open source GSM cracking software called “Kraken” has been released into the wild. You may recognize some of the information from back in December when we announced that they had cracked GSM encryption. Well, now you can participate as well. You’ll need a pretty beefy Linux machine and some patience. They say that an easier GUI and support for GPU processing is coming in the near future.

[Nikita] made a great find while cleaning out his garage: a set of audio amplifiers from a 1986 Volvo. After a bit of testing, he dislodged a stuck relay and set out to use these amps for a home audio system. He grabbed some left over brackets from his TV mount and used them as rail mounts. On the back he wired standard speaker connectors and RCA connectors to the wiring harness for the amplifiers. The final aspect is powering up the device, for which he used his ATX psu previously modified as a bench supply. 130-Watts of power for the cost of a few connectors.

[Oleg] worked out a way to use his USB mouse to control this manipulator arm. Using a Lynxmotion AL5D (we’ve seen the AL5A previously) he drives the six servos with an Arduino servo shield. A USB host shield handles the HID end for connecting the mouse. The video after the break says it all, [Oleg] has no problem picking up that figurine quickly and accurately. Sliding the mouse controls horizontal movement in all directions. The scroll wheel moves the claw up and down. And holding the left or right buttons what using the control wheel closes or rotates the claw. All we can say is: Bigger, BIGGER!

If you don’t look close you might think this Seagate Dockstar is in stock condition. But look at the three holes in the white case just above the thumb drive which act as a serial connection for the Dockstar. [Firestorm_v1] posted the instructions after see our post about installing OpenWRT on the device. He did a nice job of concealing the connection, heating up a pin header to melt the holes he needed. Now he has quick access without sacrificing features or aesthetics. A serial-to-USB cable is modified with a polarized pin header to ensure a quick and accurate connection. This is great for PC connectivity but you also never know when you want to add your own hardware bits to the network device.

This thrift shop organ gets a new life as an 8-bit music maker. Called the Chipophone, it relies on an ATmega88 to produce sounds that you might associate with classic video gaming. [Linus Akesson] takes us through all of the different sound settings in the video after the break, including performances of your theme music favorites.

The original organ uses transistor logic making it rather easy to patch into the hardware. Thanks to the build log we know that [Linus] used 74HC165 input latches to monitor each of the switches for the 120 inputs. Fifteen of these latches work like a backwards shift register 74HC595, cascading all of the parallel inputs into one serial signal. From there the microcontroller takes over, monitoring the keys, pedals, switches, and potentiometers and outputting the appropriate sounds.
